AI Technical Summary

Technical Problem

Traditional TDLAS systems have weak noise immunity, and convolutional neural networks lack a mechanism for separating noise from effective signals, resulting in a limited receptive field and low accuracy in gas concentration retrieval.

Method used

We employ an AEEMAM-DCM neural network, combined with CEEMDAN decomposition and channel attention mechanism, to adaptively separate noise from effective signals. We use deformable convolution to increase the receptive field and add a positional attention mechanism to optimize feature extraction.

Benefits of technology

It improves the accuracy and noise resistance of gas concentration inversion, realizes high-precision inversion of gas concentration and temperature, and enhances the signal-to-noise ratio and sensitivity of the system.
